Wires intended use
KVBbShv, KVBbShvng
Cables are intended for fixed connection to electrical devices, instruments, terminal boards of electrical switchgear rated up to 1 kV AC voltage and up to 100 Hz frequency.
Control armoured cables are used for laying in the ground (in trenches), premises and cable structures where protection against mechanical damage is required and no significant tensile forces are present.
